Securing Your Industrial Networks by Aligning IT and OT
In the first six months of 2013, 53 percent of cybersecurity incidents were in the energy sector, according to the Department of Homeland Security. As cyber-attacks are becoming increasingly prevalent in industries that support our critical infrastructure, it’s crucial that business leaders adopt security process designed to address these new threats. Are you ready?
While I was at CERAWeek last month, former US Secretary of Energy, Daniel B. Poneman, and Under Secretary, NPPD, US Department of Homeland Security, Suzanne Spaulding had a message to attendees. Their message was clear:
Cyber Security is a “C-Suite” topic of Enterprise Risk Management.
Their recommendations are strong: Security needs to be baked it in from the beginning! Physical and Cyber Security and Secure Coding of Software!
• Implement Layered Protection; we cannot depend on just a perimeter defense
• Apply Cyber Security Framework: 1. Assess, 2. Protect, 3. Detect, 4. Respond, 5. Recover
• Attend to the nexus of Physical and Cyber Security
• Test your response, including business recovery and continuity
Digital strategy and business strategy are becoming one and the same. Forward-looking energy firms see opportunity in today’s turbulent market and seek to pull ahead by changing their operating models through the Internet of Everything (IoE). Transformative digital technologies have to potential to deliver many advantages to O&G firms, including increased business agility and risk awareness, lower cost of operations, and reduced downtime. But before the industry can embrace these new strategies, an effective, end-to-end cybersecurity approach—including alignment between IT and OT—is needed.
Security a Catalyst for Transformation
Digital transformation means that a range of new and diverse devices are connecting to industrial oil and gas networks, generating greater amounts of data. When managed effectively, this data delivers the right information to the right place, at the right time, helping create a competitive advantage. However, as the IoE proliferates, the accompanying explosion of devices and applications will lend itself to increased areas of attack that criminals will seek exploit.
Oil and gas companies must replace traditional approaches like physical segmentation and security by obscurity. They need an integrated approach where information flows in real time to enable immediate action. Cybersecurity doesn’t need to be an inhibitor. It should be the catalyst for new ways of working. It can help oil and gas companies work more safely and better protect the environment by obtaining remote visibility and control over operations, including processes in refineries. It can make processes more efficient, increase production and reduce overall costs.
Addressing the Entire Threat Continuum
Cyber-attacks occur on a continuum of before, during, and after. The same digital hyper-connectivity that oil and gas managers use to collect data and control machines and processes, can also allow cyber attackers to get into system networks and steal or alter classified information, disrupt processes and cause damage to equipment. Threats to a company’s information systems and assets could come from anywhere. State and non-state actors from around the globe are constantly working to penetrate the networks of energy providers and other critical infrastructures in the U.S.
Energy firms must address this entire continuum with a visibility-driven, threat -focused, and platform-based framework:
- Visibility-driven means having an accurate, real-time view of the network fabric, endpoints, mobile devices, applications, virtual environments, the cloud, and their interrelationships. High visibility allows you to make sense of billions of devices, applications, and their associated information, while helping you see an attack coming, control the environment, and mitigate threats.
- Threat-focused means focusing on detecting, understanding, and stopping threats. Policies and controls reduce the surface area of attack, but threats still get through. Focusing on threats can help you identify threats and indicators of compromise based on a well-honed understanding of normal and abnormal behavior. This requires continuous analysis and real-time cybersecurity intelligence across all technologies. With contextual awareness, you can identify false-positives and assess the impact of a threat.
- Platform-based means we have an integrated system of agile and open platforms that cover the network, devices and the cloud. It is a true platform of scalable, easy-to-deploy services and applications. You gain powerful end-to-end visibility with centralized management for unified policy and consistent controls
Securely Converge IT and OT
As oil and gas companies embrace the IoE, they bring together the use of information technology (IT) and operational technology (OT). Security needs to be as pervasive and applied in a unified way across the extended network. Physical and cybersecurity solutions must work intelligently together to reduce unauthorized system access – in order to protect networks, devices, applications, users and data. For example, in many oil and gas companies today, upstream and downstream domains use different solutions for common tasks such as asset performance management. In addition, OT is often managed autonomously from IT, even for critical functions such as reliability and cybersecurity.
Cisco has the broadest set of solutions covering the broadest set of attack vectors, leveraging both global and local intelligence. Cisco’s Secure Ops Solution is helping oil and gas companies secure industrial control networks by combining on-premises technology, processes, and managed services. For example, Royal Dutch Shell (Shell) was challenged with increasing its security maturity level. By implementing the Secure Ops Solution, Shell was able to improve its cyber security and risk management, lowering costs of delivery while significantly reducing its costs of securing the process control systems that keep billions of pounds of toxic material under control. Cisco Secure Ops Solution provides remote proactive monitoring and Service-Level-Agreement (SLA) driven management of security, applications and infrastructure, making it easier to:
• Manage cyber-security risk.
• Support compliance.
• Secure the perimeter between enterprise and operational networks.
• Implement and maintain layered security controls
